Be it known that we, WILLIAM F. WOLLIN and ELMER H. .WERLINE, citizens of the l UnitedStates, residing at York, in the county of York and State of Pennsylvania,.h ave invented certain new and useful Improvements j in Electric-Lamp Sockets with Regulating Attachment; 'and we do hereby declarethe fol= lewin g to be a full, clear, and exact description 1o of the invention', such as will enable others skilled in the '.artto which `it appertains to vmake and usethe same.' l, y I

The object of -ths invention is to provide means for controlling .the intensity of the light of an incandescent electric lamp, so that it may be of any-degree desired, as is the case with the flame of 'an ordinary gas-burner. To' this end-we make use of devicessubstan-v tially as hereinafter set forth and claimed;A 2o In the accompanying drawings, Figure 1 represent-sa perspectiveview `of a burner with our regulating attachment. Fig. 2 rep-` resents a vertical centralsection through the same. Fig'. 3represents ahorizontal section through the same on-the line'ca; of Fig. 2. Figs. fi and 5 are detail views. Fig. 6 is a diagram illustrating the circuits and opera-1. tion.

- A designates 3o having within it the globe of an electric lampy' the usual carbon filament or 1 platinum wire a, one end of which is attached to a metallic sleeve A', encircling the neck of said globe, the other endbeing attached to a; metallic block or cylindrical piece A2, that is; itted centrally into the end of said neck andinsulated from said sleeve by a' mass A3 of paster-of-paris or other nonconducting ma.l terial.

The sleeve A is screw-threaded, as usual, to entera socket B, which consists of a metallic shell B', internally screw-threaded and surrounded` at its upper end by a collar b, of vulcanized rubber or other insulating ma-v teria-L An insulating-disk B2 is fastened to the lower end of. this shell and forms the base of the socket. A metal block B extends up through. the central part of this diskvfor contact with the similar block A2, already` mentioned, at the lower end of the neck of 5o the globe. The sleeve A' and shell -B' are of course in electrical contact.

From the block B a wire C descends to a;

binding-screw d on a plate D, which. has another binding-screw d forthe attachment of a'circuit-wire E.-l The corresponding circuit-wire E is attached to a-screw e on a sec-A plate D, and having A ond plate F-,similar to another binding-screw e for a'wire G, which extends to a spring or other electrical couductor H incontact with the metal shaft ci `of a rotary key .or governor I. AThe plates D F are,l separated'by and attached toa'n insulating-blcckJ, which is, inclosed by and'fastcned tothe spreadflo'wer 'ends of -a central standard jK, preferably j formed 'of ltwo dat plates arranged and held against each other; 'Theltipper endsof these plates also diverge andsnpport the insulating-disk B2,'already mention'edil The governor I turnslinjan insulating-strip side loffl-afrirarne' gc'onsistingJ .of I n 'p- -right 'rods'land top and bottmrings L L,f'll

'of 4metal. This frame has below'it a basering M, of vulcanized rubber or other insulating material, and has also fitted on the top of its upper ring L a lating material, surrounding recessed to receive said ring. .insulating basering and insulatlngcrown Wires are wound lengthwise of the frame, so as .to give the device the aspect of a cage. These the disk B2 and crown M', of similar insu` Over the said 'Wires furnish the' resistance whereby the inteusity of the light is determined.A As illustrated, they are six in number1, 2, 3, 4, 5, and 6-each constituting 'a section of "the resistance, and connected by one of several studs 'n n', dac., to the next section or wire-that is, Wire l is wound at eachend around such a stud; wire 2 iswound at one end around the Y same stud that one'v end of wire l is wound around; wire 3 :is Wound at one end around the stud which receives the other end of wire 2, and so on throughout4 the series. These studs-71l n', dac., are attached to the baser-ing M at il'itervals corresponding to' the ends of theseveral resistance-wires. They are six in number, (ndicated'by n' n' fn.2 n3 'n4 m5,) and each is connected by a Wire o, 02,02, 0.3, 0*, or o5 to a contact-stud p p' p2 p3 p4 p5, attached to the insulating-strip l. These studs are arranged in a circle, or approximately so, and `collectively'constitute a switch-board. -The governor or "key I is provided with a "radial arm l', 'which moves over this circle as ICC fla-f the'said key is'turned,and by being in co'ntact with one oran-other ofls'aid contact-studs determines the number ofwires -12,- dto., vvvjhieh-fshallbein-.the'circuit.'
